87 power steering pump replacement didn't work

[bennylava]

Hi all. I Just replaced my power steering pump in my 87 Silverado 5.7L 2wd. My power steering had stopped working, and all the fluid was in the driveway. Couldn't find any leaks, so I removed the old pump to have a look at it. The old one was leaking around the big main seal. At least it seemed to be once I got it off of there. So I went ahead and put the new reman pump on there that I got from the local parts store.

Unfortunately it doesn't seem to work. This is after I spent about 45 minutes turning the wheel left to right, in an effort to bleed the system. I turned the wheel with the tires on the ground for about 20 minutes, and then I got tired. So I jacked up the front and kept at it. Still no power steering. And every time I'd turn the steering wheel, it would lose a bunch of the fluid out of the top. Fluid would just start pouring out of the filler neck, as if there was too much fluid in it or something. I finally got it to take some fluid and keep it, but I still have no power steering. Makes me wonder if some other problem was causing the old pump to spew out all its fluid too.

The steering gear box is new, it might have 1,000 miles on it. Plus that wasn't a problem before the pump quit working. Could it be that the system just has a lot of air in it? It seems like 45 minutes worth of turning the wheel would be more than enough to remedy that situation. Not sure what to do now.
